| Abstract | The study of oceans and atmosphere has acquired significant importance to explain the climate variability and climate change. Currently, researchers have used diverse oceanic and atmospheric models to carry out forecasts and try to understand the climate past. Water masses acquire their signatures from atmospheric processes and are therefore excellent indicators of alterations in climatic conditions. This work aims to inter-compare the behavior of deep water masses between different models output and the real pattern observed in the oceans, such as the main distribution displayed during the WOCE program. With this we aim to understand how the ocean internal variability and the interactive ice-model will affect the representation of the current oceanic characteristics. OMP analysis was used to trace the deep water masses in the Weddell Sea - Antarctic (water masses source region). The following water masses were considered: Warm Deep Water (WDW), Weddell Sea Deep Water (WSDW) and Weddell Sea Bottom Water (WSBW). Thermohaline index parameters used to run OMP had been gotten from historical hydrographic data obtained in study area. Three different models output have been analyzed: 1- POP3 (ocean only model forced with observed 43 years of NCEP/NCAR winds with corrected fluxes over ice-covered regions (Large and Yeager)), 2 - POP3 (ocean only model forced with a repeat annual cycle of observed NCEP/NCAR winds and fluxes), and 3 - POP3 (ocean model coupled to an interactive ice-model forced with the same repeat annual cycle of observed NCEP/NCAR winds and fluxes). The preliminary results show a good correlation between the present observed WOCE distribution and the results obtained by output 3, indicating the importance of including an ice-model in order to represent the dense water masses. The analysis for the other two ocean-only models shows a super-estimation of the WSBW. This may be associated with the parameters indices utilized. Results may be improved if a different definition for source water-type is used within the OMP analysis therefore TS structure for each case is examined. Considering the subsampling in the WOCE data, model output is also compared to the SODA ocean assimilation product (Carlton and Giese). | |||
